Dexcessa, the Talon of Slaanesh

Dexcessa, the Talon of Slaanesh, was born in a single perfect instant, spat from the Dark Prince's prison at the moment the chained god first strained against its bonds. Where its twin, Synessa, took the form of speech, Dexcessa was made of movement: a lithe, winged rapture of a being, restless and radiant, that has not been still since the heartbeat of its creation.

It fights as a dancer fights, if a dance could kill. Wielding the Living Whip and a coterie of shard-like blades, Dexcessa spins through the enemy in a blur of wings and laughter, every stroke a flourish, every kill a note in some private symphony only it can hear. Around it swirls the raw, intoxicating essence of Slaanesh, and mortals who draw too near are swept up in an ecstasy that leaves them helpless before its claws.

Dexcessa exists for one purpose above the pleasure of slaughter: to free its imprisoned parent. It ranges the realms at the head of the Dark Prince's hosts, a firstborn scion hunting for any thread that might lead to the Hidden Gloaming where Slaanesh lies bound, and it dances toward that goal with the joyous, single-minded abandon of a creature that has known nothing else.
